Diagnostic Test
1.ACTIVE DTC
NOTE: The most likely cause of this DTC is a plugged intake air system or Dirty Throttle Body. Check for
TSB’s before continuing.
NOTE: Diagnose any 5-Volt Supply, TP Sensor, Fuel System Lean or Rich, or MAP Sensor DTCs before con-
tinuing.
NOTE: The throttle plate should be free from binding and carbon build up.
NOTE: Question the customer about weather conditions, as ICE build up on the blade can cause this fault
when ambient is around +4 to -10 Celsius range.
Ignition on, engine not running.
With a scan tool, read DTCs.

1.ACTIVE DTC
NOTE: The most likely cause of this DTC is a plugged intake air system or dirty Throttle Body. Check for
any TSB’s before continuing.
NOTE: Diagnose any 5-Volt Supply, TP Sensor, Oxygen Sensor, Fuel related or MAP Sensor DTCs before
continuing.
NOTE: The throttle plate should be free from binding and carbon build up.
NOTE: Question the customer about weather conditions, as ICE build up on the blade can cause this fault
when ambient is around +4 to -10 Celsius range.

Refer to the INTERMITTENT CONDITION Diagnostic Procedure.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)

When Monitored:
Ignition on, Engine running, and no ECT DTCs present.
Set Condition:
PCM recognizes that the ECT has failed its self coherence test. The coolanttemp should only change at a
certain rate, if this rate is too slow or too fast this fault will set. Two trip fault. Three good trips to clear MIL.
ETC light will illuminate on first trip failure.
Possible Causes
LOW COOLANT LEVEL
(K2) ECT SIGNAL CIRCUIT SHORTED TO BATTERY VOLTAGE
(K2) ECT SIGNAL CIRCUIT OPEN
(K900) SENSOR GROUND CIRCUIT OPEN

Diagnostic Test
1.ACTIVE DTC
Ignition on, engine not running.
NOTE: If this code sets during extreme ambient temperatures, improper installation of a block heater could
be the cause of this DTC.
With a scan tool, read DTCs.
Diagnose all other ECT and Cooling System codes before continuing.

No>>
Refer to the INTERMITTENT CONDITION Diagnostic Procedure.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)
2.LOW COOLANT LEVEL
NOTE: If a Engine Coolant Temperature (ECT) DTC is set along with this code,diagnose the ECT DTC first.
NOTE: Inspect the ECT terminals and related PCM terminals. Ensure the terminals are free from corrosion
and damage.
NOTE: The best way to diagnose this DTC is to allow the vehicle to sit overnight outside in order to have
a totally cold soaked engine.
NOTE: Extremely cold outside ambient temperatures may have caused this DTCtoset.
NOTE: Need to make sure that no Cooling System DTCs are set or changes that would make the warm up
much slower or much faster: broken water pump can set this, addition of aftermarket auxiliary cooler can
set this DTC.
WARNING: Never open the cooling system when the engine is hot. The system isunder pressure. Failure to
follow these instructions can result in personal injury or death. Allow the engine to cool before opening the
cooling system.

For a complete wiring diagramRefer to Section 8W.
When Monitored:
Ignition on. No Break or APPS faults present.
Set Condition:
The PCM recognizes a brake application following the APPS showing a fixed pedal opening. Temporary or
permanent. Internally the PCM will reduce throttle opening below driver demand. One trip fault and the code
will be set within 5 seconds. ETC light will illuminate, the light will onlystay illuminated while DTC is active.
Possible Causes
CUSTOMER PRESSING ACCLERATOR PEDAL, THEN PRESSING BRAKE PEDAL, AND CONTINUES
HOLDING THEM DOWN SIMULTANEOUSLY
STOP LAMP SWITCH
APP SENSOR
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING).
Diagnostic Test
1.DTC INFORMATION
NOTE: If a pedal assembly becomes mechanically stuck the voltage output will stay fixed, if this is also
Followed by a long application of the brakes this code will set.
NOTE: When this code sets the pedal position in the PCM software will ramp toidle. If the Pedal voltage
changes OR the brake pedal is released, the pedal position in the PCM software will ramp up to the pedal
position and the ETC light will go out.
With a scan tool, read DTCs and record the related Freeze Frame data.
Diagnose all other Stop Lamp Switch and APP Sensor codes before continuing.
This code can be set by a driver who uses both feet while driving, one for the Accelerator Pedal and the other for
the Brake Pedal.
NOTE: The most likely cause of this DTC is caused by the customer Brake Torquing the engine by pressing
the Accelerator pedal and the pressing the Brake Pedal.
Ask the driver of the vehicle if these conditions apply to their driving habits.
Are the listed conditions part of the customers driving habits?
